Astrônomos Confirmam Existência de Água nos Pólos do Planeta Anão Ceres

 Ceres is only the third planetary body, after the Moon and Mercury, where water ice has been found. Craters at Ceres' poles (pictured) are permanently engulfed in darkness, and these spots are cold enough to have been collecting ice over billions of years 
Craters at Ceres' poles are permanently engulfed in darkness, and these spots are cold enough to have been collecting ice over billions of years. In this graphic, the blue regions show the darkened craters where the ice has formed
Even the indirect sunlight that reaches the poles never heats it up to more than minus 151 degrees Celsius (minus 240 degrees Fahrenheit), making both the poles a 'cold trap'. This graphic shows another angle of the cold traps, in blue, where ice forms

Ceres is the largest body in the asteroid belt between Mars and Jupiter and the only such object classed as a dwarf planet. Nasa's Dawn spacecraft (illustrated) has been in orbit around Ceres for more than a year, and the latest Ceres study used the probe's Framing Camera
